Definitions
- a data processing apparatus and a computer implemented method for rendering a tree structure of elements are presented.
- the present disclosure relates to a data processing apparatus and a computer implemented method for rendering a tree structure of elements in a graphical user interface depending on a position of a pointing cursor relative to the rendered tree structure, and to a corresponding computer readable storage medium.
- a vehicle taxonomy may comprise the sub- concepts ground vehicle, watercraft, aircraft, etc., with the ground vehicles further comprising sub-concepts like car, truck, bus, etc.
- any sub-concept is a kind of all of its super-concepts. Therefore, if a specific concept to be annotated is missing in a taxonomy, an annotator can fall back to the best matching super-concept.
- a battle tank may be annotated as ground vehicle, and a UFO
- (unidentified flying object) may be annotated as vehicle.
- a large and complex taxonomy can have several independent top-level concepts, lots of levels of hierarchy beneath each top-level concept, and many sub-concepts of single super-concepts. This huge amount of deeply nested concepts can be difficult to render conveniently in a graphical user interface (GUI) of an application using this taxonomy, e.g. in a view showing this taxonomy for selection of concepts to be annotated.
- GUI graphical user interface
- each top-level concept may get its own table or be the header of a table column or row.
- a column header shows a super-concept and the content of the column the
- columns may contain sub-tables, e.g. with a direct sub-concept shown in bold face and its lower-level concepts shown in normal face.
- Such a table view can show many concepts and their hierarchy in small space and can provide a good overview of the concepts. However, it can only show a few levels of hierarchy at a time without getting confusing. If a user needs to review further sub-levels, the user must select a concept for which further sub-levels are to be shown, e.g. by updating a currently shown table or showing an additional table. In a deeply nested taxonomy, multiple such selections may be necessary to reach a specific concept.
- Another possibility to render taxonomies is to employ a tree view.
- Such views are used to show deeply nested hierarchies in various applications, e.g. file system explorers or document outlining tools.
- Such applications may provide controls to extend/reduce a currently shown number of tree levels beneath a selected one by one or more levels, expand/collapse all tree levels beneath a selected one, collapse a specifically configured sub-tree to a selected level and afterwards show this sub-tree as previously configured again, show a specific number of tree levels beneath the top level, etc.
- a tree view with such functionality can also be used to render taxonomies so that a user can browse and expand the sub-trees of interest to find and select a concept of interest.
- Such a tree view can render huge taxonomies with many levels of hierarchy. However, it is less suitable for providing an overview of the concepts: If many tree levels are expanded, much scrolling is needed to find a concept in the spread-out view, and it is hard to keep track of concept relationships. If, for a more compact view, only few tree levels are expanded, many expand/collapse operations are needed to drill down to or up from low-level concepts.
- a GUI of an application using taxonomies may contain table views, but a table view can hardly handle a high number of hierarchy levels of a large taxonomy properly, causing a need for frequent updating of the table view or showing of child tables quickly.
- a manually adjusting the table view of a large taxonomy can hardly handle a high number of hierarchy levels of a large taxonomy properly, causing a need for frequent updating of the table view or showing of child tables quickly.
- configurable tree view is used for large taxonomies, but this lacks convenience due to the compact overview vs. required amount of view reconfiguration operations issue.
- the same problem applies not only to searching for concepts in a taxonomy, but also for elements in other complex tree views, e.g. to searching for a file in a deeply nested file directory structure or for a database entry in a deeply nested database structure.
- GUI graphical user interface
- a computer implemented method for rendering a tree structure of elements in a graphical user interface depending on a position of a pointing cursor relative to the rendered tree structure comprises
- the position of the pointing cursor relative to the tree view consisting of a first position value according to a first direction and a second position value according to a second direction orthogonal to the first direction;
- a graphical representation unit configured to generate a tree view of the tree structure being organized in a plurality of branches
- a position determination unit configured to determine the position of the pointing cursor relative to the tree view, the position consisting of a first position value according to a first direction and a second position value according to a second direction orthogonal to the first direction;
- an active branch selection unit configured to automatically select the branch the position of the pointing cursor is aligned with according to the first direction as an active branch
- an expansion determination unit configured to determine sub-levels of the active branch to be expanded, depending on the second position value relative to
- the graphical representation unit being further configured to automatically update the tree view by expanding the determined sub-levels of the active branch and collapsing other branches.
- Units comprised in the apparatus such as the graphical representation unit, the position determination unit, the active branch selection unit and the expansion determination unit may be provided as separate devices, jointly as at least one device or logic circuitry, or functionality carried out by a microprocessor, microcontroller or other processing device, computer or other programmable apparatus.
- a data processing apparatus for rendering a tree structure of elements in a graphical user interface depending on a position of a pointing cursor relative to the rendered tree structure comprises
- the pointing cursor determines the position of the pointing cursor relative to the tree view, the position consisting of a first position value according to a first direction and a second position value according to a second direction orthogonal to the first direction;
- the devices are connected by a bus or other communication lines.
- a computer readable storage medium has stored therein instructions enabling rendering a tree structure of elements in a graphical user interface depending on a position of a pointing cursor relative to the rendered tree structure, which, when executed by a computer, cause the computer to:
- the pointing cursor determines the position of the pointing cursor relative to the tree view, the position consisting of a first position value according to a first direction and a second position value according to a second direction orthogonal to the first direction;
- the computer readable storage medium tangibly embodies a program of instructions, which, when executed by a computer, cause the computer to perform the described method steps.
- the graphical user interface is responsive to user input controlling the position of the pointing cursor relative to the rendered tree structure of elements.
- the pointing cursor can be moved or manipulated using a pointing cursor manipulation device, for example a computer mouse, trackball, trackpoint or touchpad. If the display device is a touchscreen device, the pointing cursor can also be moved or manipulated using, e.g., a finger of the user or a stylus. In an embodiment the pointing cursor can be moved in response to hand or finger tracking and gesture recognition during analysis of a live video provided by a camera showing the user.
- the tree structure is organized in, i.e. comprises, a plurality of branches or paths of connected nodes, which may consist of sub-levels, i.e. tree-levels beneath a parent node, wherein the elements or nodes contained in a sub-level are connected to a same indentation as siblings of a same parent node.
- the tree view is a graphical representation of the tree structure.
- the tree view is shown in a GUI element, e.g. a window or frame. It allows automatic selection of the active branch, i.e. the position of the pointing cursor is determined without clicking, just by evaluating the position of the pointing cursor relative to the tree view.
- the active branch is the branch which is selected to be explored by the user, e.g. by expanding sub-levels. This relative position of the pointing cursor can be changed, either by moving the pointing cursor over the tree view or by scrolling the viewing window showing the tree view, while the absolute position of the pointing cursor, i.e. the position in relation to the borders of the viewing window or the screen of the display device displaying the viewing window containing the tree view, may or may not remain unchanged.
- an automatic tree view reconfiguration mechanism causes the automatic updating of the tree view by expanding the determined sub-levels of the active branch and collapsing the other branches.
- the automatic tree view reconfiguration mechanism allows to quickly examine a complex tree like data structure. It mimics the behavior of a user using manual controls to browse nested data, e.g. of a taxonomy, a file system or a database, being organized in a tree structure and displayed as tree in a tree view, to find and select an element of interest, i.e.
- the mechanism uses the position of a pointing cursor with respect to the tree view to control which branches of the tree to expand/collapse automatically. It reconfigures the tree view for a compact presentation of the tree without the need for explicit expand/collapse operations by mouse clicks, keystrokes, touchscreen taps, or similar, and needing less pointing cursor movements than necessary for a corresponding manual control scheme.
- the mechanism according to the proposed solution at least has the effect that a user can perform the task of finding/selecting an element of interest in a faster and more convenient way than by using manual controls, i.e., a more efficient man-machine interface is provided.
- the first direction corresponds to a vertical direction and the second direction corresponds to a horizontal direction on a screen of a display device displaying the tree view in the graphical user interface.
- the vertical position of the pointing cursor with respect to the tree elements is used to control which branch of the tree is selected as the active branch that may be expanded, and the horizontal position of the pointing cursor with respect to the indentations of the tree levels is used to control how many sub-levels of the active branch will be expanded.
- a sub-level of the active branch is determined as to be expanded, if the indentation of the sub-level is found left of the position of the pointing cursor.
- the first direction corresponds to the horizontal direction and the second direction corresponds to the vertical direction.
- the determining of the position of the pointing cursor, the automatic selecting of the active branch, the determining of sub-levels to be expanded and the automatic updating of the tree view are continuously repeated.
- the automatic mechanism constantly tracks any movement of the pointing cursor and, if necessary, immediately automatically reconfigures the tree view for a compact presentation of the tree.
- a short delay can be introduced before automatically performing the expand/collapse operations.
- the expand and/or collapse operations are delayed until an additional keystroke, e.g. of an arrow key, has been performed.
- the tree view is updated by collapsing an exceeding sub-level of the active branch and the updated tree view is moved, automatically without further user interaction, in the first direction until a corresponding element hiding, i.e.
- the collapsed exceeding sub-level becomes aligned with the position of the pointing cursor according to the first direction, if an amount of the sub-levels to be expanded is less than an amount of currently expanded sub-levels. In other words, if the displayed position of the pointing cursor becomes inconsistent with the
- the updated tree view is automatically moved in the first direction, e.g. vertically, so that the actual pointing cursor position reflects the new logical pointing cursor position with respect to the updated tree view.
- first direction is the vertical direction and the pointing cursor is not vertically aligned with a direct or indirect super-element of the tree level being collapsed due to moving the pointing cursor to the left, simply collapsing this tree level otherwise may cause an arbitrary tree element, if any at all, to be vertically aligned with the pointing cursor, depending on the space previously occupied by the elements of this tree level and the vertical position of the pointing cursor with respect to these elements.
- the tree structure of elements corresponds to a taxonomy, i.e. a classification scheme of concepts, e.g. concepts from taxonomies used for multimedia data.
- the graphical user interface with the interactive tree view corresponds to a taxonomy browser for hierarchical metadata, i.e. a taxonomy is rendered in the GUI, e.g. for semantic metadata annotation to multimedia data.
- the automatic tree view reconfiguration mechanism adapted to the task of finding and selecting a concept in a taxonomy displayed as tree in a tree view according to the proposed solution allows efficient rendering of even large taxonomies.
- the tree structure of elements corresponds to a directory structure of files.
- the automatic tree view reconfiguration mechanism according to the proposed solution can also be used for tree views showing other content than taxonomies in various applications if the intended use of these views is to quickly browse to and select an element of the tree.
- any database, document outlining tool, file explorer or an "Open File" dialog containing a tree view using the proposed tree view reconfiguration mechanism may need fewer control operations to find and select an element compared to applications using a standard tree view needing explicit operations to expand/collapse sub-trees, e.g. subfolders.
- the tree view is updated in response to further manual user input to the graphical user interface in the manual mode.
- An apparatus carrying out the method according to the proposed solution can provide both manual tree view configuration functionalities and the proposed automatic mechanism, with a means to switch between the two modes.
- it stores the manually established view configuration when the automatic mode is switched on and restores the previously stored configuration when the automatic mode is switched off again.
- the pointing cursor is generated specifically for user interaction with the tree view. This applies, e.g., to systems not using a standard pointing cursor.
- a standard pointing cursor For devices which use, e.g., a mouse pointer as their standard input, scrolling solutions not dependent on scroll bars can be provided, whereas touchscreen- controlled devices not using such a standard pointing cursor can use the standard swiping gestures for scrolling.
- the pointing cursor position is defined by the position of this pointing cursor.
- a standard pointing cursor e.g.
- a pointing cursor specifically dedicated to the viewing window of the tree view is used instead.
- the position of this dedicated pointing cursor is controlled by dragging the pointing cursor over the viewing window, e.g. by a user's finger or a stylus.
- an application using this automatic mechanism does not use standard scroll bars at the edges of the viewing window to scroll the view, because moving the pointing cursor across the tree view to access such scroll bars may cause reconfigurations of the view.
- other scroll control means are used, e.g. keyboard controls, the mouse wheel (e.g.
- a touchscreen-controlled application can use standard swiping gestures on the viewing window to scroll the view, provided that a swiping gesture does not start at the pointing cursor position, which could be interpreted as dragging the pointing cursor instead.
- the tree view comprises visual indications whether or not a tree element corresponds to an indentation and has sub-elements, i.e. hides a sub-tree.
- the visual indications can be icons, such as a plus, a right-pointing triangle or an arrow.
- the visual indications can be given by rendering tree elements in different styles, e.g. different color or typeface, bold/italic or not, etc.
- the visual indications additionally comprise a graphical suggestion of the complexity of the not-yet-expanded levels or sub-trees, such as a number or a bar indicating an amount of hidden elements.
- one or more position indicators visualizing a position of a visible section of the tree structure with respect to the tree view are shown as part of the viewing window. This provides navigation information, for example when scrolling the view or automatic reconfiguration of the view has led to no part of the tree view actually being visible within the viewing window.
- Position indicators can be, for example, scroll bars, small lines with a broader part indicating the position, and/or plain lines indicating the position with respect to the height/width of the viewing window. If the position indicators provide scroll control functionality, they are not used for scrolling the viewing window to avoid potentially undesired reconfiguration of the tree view on moving the pointing cursor across the view.
- the position indicators are shown in a separate window or frame of the graphical user interface.

- FIG. 1 an embodiment of a computer implemented method 10 for rendering a tree structure of elements in a graphical user interface depending on a position of a pointing cursor relative to the rendered tree structure is schematically shown.
- the method provides an automatic mechanism that constantly reconfigures the tree view for a compact presentation of the tree.
- a tree view of the tree structure which is organized in a plurality of branches, is generated.
- a selection between an automatic mode and a manual mode is performed in response to a mode selection input by the user.
- the tree view is updated in a next step 13 in response to further manual user input to the graphical user interface.
- a next step 14 the position of the pointing cursor relative to the tree view is determined.
- the position consists of a first position value according to a first direction and a second position value according to a second direction orthogonal to the first direction.
- a next step 15 the branch the position of the pointing cursor is aligned with according to the first direction is automatically selected as an active branch.
- sub-levels of the active branch to be expanded are determined depending on the second position value relative to indentations of the sub-levels.
- a next step 17 the tree view is automatically updated by expanding the determined sub-levels of the active branch and collapsing the other branches. If the position of the pointing cursor relative to the tree view is continued to be changed in a next step 18, the pointing cursor position determination step 14, the active branch selection step 15, the sub-level expansion determination step 16 and the automatic tree update step 17 are continuously repeated. Otherwise, in the shown embodiment the method waits for any more position change of the pointing cursor relative to the tree view.
- FIG. 2 and Fig. 3 embodiments of data processing apparatuses for rendering a tree structure of elements in a graphical user interface depending on a position of a pointing cursor relative to the rendered tree structure are schematically shown.
- the apparatus shown in Fig. 2 and the apparatus shown in Fig. 3 allow implementing the advantages and characteristics of the described method for rendering a tree structure as part of an apparatus for rendering a tree structure of elements in a graphical user interface depending on a position of a pointing cursor relative to the rendered tree structure.

- the graphical representation unit 23 updates the tree view in response to further manual user input to the graphical user interface.
- the graphical representation unit 23 updates the tree view in response to input from at least an expansion determination unit 27.
- a position determination unit 24 is connected to the graphical representation unit 23 and is configured to determine a position of the pointing cursor relative to the tree view.
- the position consists of a first position value according to a first direction and a second position value according to a second direction orthogonal to the first direction.
- the position is determined based on input 25 from the user controlling the position of the pointing cursor by scrolling or moving the pointing cursor.
- An active branch selection unit 26 is configured to automatically select the branch the position of the pointing cursor is aligned with according to the first direction as an active branch, and an expansion determination unit 27 is configured to determine sub- levels of the active branch to be expanded, depending on the second position value relative to indentations of the sub-levels.
- the graphical representation unit 23 is configured to automatically update the tree view by expanding the determined sub-levels of the active branch and collapsing the other branches.
- the selection unit 21 , the graphical representation unit 23, the position determination unit 24, the active branch selection unit 26 and the expansion determination unit 27 directly communicate with each other.
- the apparatus comprises a controller unit connected to one or more of the units and controls their communication.
- the selection unit 21 , the graphical representation unit 23, the position determination unit 24, the active branch selection unit 26 and the expansion determination unit 27 may be provided as separate devices, jointly as at least one device or logic circuitry, or functionality carried out by a microprocessor, microcontroller or other processing device, computer or other programmable apparatus arranged to perform the
- processing connected to or comprising at least one memory device.
- an embodiment of a data processing apparatus 30 for rendering a tree structure of elements in a graphical user interface depending on a position of a pointing cursor relative to the rendered tree structure comprises a processing device 31 , a display device 32 and a memory device 33 storing instructions that, when executed, cause the processing device to
- - generate a tree view showing, using the display device 32, the tree structure being organized in a plurality of branches; - determine the position of the pointing cursor relative to the tree view, the position consisting of a first position value according to a first direction and a second position value according to a second direction orthogonal to the first direction;
- the processing device can be a processor adapted to perform the steps according to one of the described methods.
- said adaptation comprises that the processor is configured, for example programmed, to perform steps according to one of the described methods.
- a taxonomy tree view being subject to the automatic tree view reconfiguration mechanism during user interaction via a pointing cursor in the automatic mode is schematically illustrated.
- Fig. 4 shows an example of a tree view of a taxonomy tree in a viewing window, currently having four sub-levels expanded.
- the position of the pointing cursor is indicated by an arrow.
- the taxonomy displayed as tree in the tree view has 9 top-level concepts (Concep Concept_9) with each super-concept or parent node/element having 9 sub-concepts or child nodes/elements, with 5 levels of hierarchy in total.
- this taxonomy is manipulated.
- Fig. 4 only the branch the pointing cursor is vertically aligned with is expanded while the other branches are collapsed, providing a compact presentation of the tree although tree elements up to level 5 are visible.
- the position of the pointing cursor with respect to the tree view is used for controlling the automatic expand/collapse operations of the tree view.
- the vertical position of the pointing cursor with respect to the tree elements controls which branch of the tree may be expanded as the active branch.
- the other branches of the tree are collapsed automatically.
- the horizontal position of the pointing cursor with respect to the indentation of the tree levels controls how many sub-levels of the active branch may be expanded.
- the updated tree view may also automatically be moved vertically so that the actual pointing cursor position reflects the new logical pointing cursor position with respect to the updated tree view.
- Fig. 5 shows the tree view when the pointing cursor does not point to the viewing window.
- the pointing cursor is the system's pointing cursor, i.e. a standard pointing cursor not specifically created for interacting with the tree view.
- the pointing cursor is the system's pointing cursor, i.e. a standard pointing cursor not specifically created for interacting with the tree view.
- there is no active branch by definition regardless of the vertical position of the pointing cursor. Therefore, only the top-level elements of the tree are displayed.
- the tree is always displayed with its topmost element at the top left corner of the viewing window, including associated sub- element indicators if applied to the top-level tree elements. This provides the user with a compact and consistent presentation of the tree as starting point for navigation through the tree when the pointing cursor is moved into the viewing window. Such movements may already cause an automatic reconfiguration of the tree view, depending on the position at which the pointing cursor enters the viewing window with respect to the tree view and the direction of the movement.
- Fig. 6 illustrates a situation when the pointing cursor points to the viewing window but is not vertically aligned with any tree element. No branch is selected as the active branch, resulting in only the top-level elements of the tree being displayed, too.
- the tree view does not change.
- moving the pointing cursor into the viewing window from the top causes the entering position to be vertically aligned with the topmost tree element, unless there is no tree to be displayed at all.
- the branch this element belongs to is the active branch. How many sub-levels of the active branch may be expanded depends on the horizontal position of the pointing cursor.
- this position corresponds to the top tree level, referred to as tree level 1 , i.e. if the pointing cursor is placed left of the indentation of tree level 2, only the top-level element of the active branch is displayed, together with the top-level elements of the inactive branches, see Fig. 7. From the position shown in Fig. 7, the pointing cursor can be moved up and down within the viewing window without changing the tree view. Just whether or not there is an active branch and which top-level tree element is associated with the active branch changes with the vertical displacement of the pointing cursor with respect to the tree view.
- the next sub-level of the active branch is expanded automatically if existent. If the pointing cursor is vertically aligned with a direct super-element of the tree level being expanded, this next sub-level naturally is the sub-level of this direct super-element. Otherwise, this next sub-level is defined to be the sub-level of the topmost tree element of the lowest currently expanded tree level of the active branch. For example, if the pointing cursor is moved to the right by a distance equivalent to one level of tree indentation in the tree view shown in Fig. 7, the resulting tree view corresponds to Fig.
- tree level 2 of the active branch is expanded automatically once the pointing cursor crosses the indentation of tree level 2 on its way.
- more and more sub-levels of the active branch are expanded once the corresponding indentations are crossed, resulting in the reconfigured tree view shown in Fig. 9, with the resulting horizontal pointing cursor position intentionally corresponding to tree level 6 to illustrate that moving the pointing cursor to further indentations right of the indentation of the lowest tree level of an active branch does not cause any more changes to the tree view.
- a user will not expand more than one sub-level of the active branch at one time but will first browse the tree elements of a recently expanded sub-level to see whether there is an element of interest and whether he wants to expand a sub-level beneath this element. For example, if a user decides to expand the sub-level beneath Concept_3_3 in the tree view shown in Fig. 8, he will probably move the pointing cursor down to Concept_3_3 to make the branch comprising Concept_3_3 the active branch, see Fig. 10, and then move the pointing cursor to the right to expand the next sub-level, see Fig. 1 1 . If the user continues to expand the sub-level of every third element of each tree level in the tree view shown in Fig. 1 1 , the tree view will finally correspond to Fig. 4, except for being clipped by the bottom edge of the smaller viewing window.
- this tree level is collapsed automatically. If the pointing cursor is vertically aligned with a direct or indirect super-element of the tree level being collapsed, the active branch does not change. For example, if the pointing cursor is moved to the left by a distance
- the updated tree view is automatically moved vertically so that the direct super-element of the tree level having been collapsed is vertically aligned with the pointing cursor in this case, with the same vertical displacement of this super-element with respect to the pointing cursor as the tree element the pointing cursor was vertically aligned with before the update of the tree view, as this position is the new logical pointing cursor position within the updated tree view.
- This also makes the branch comprising this super-element the active branch, enabling seamless further navigation through the tree.
- Another approach would be to move the pointing cursor to the position of this super-element instead, which is assumed to be confusing for the user. Furthermore, this super-element may currently not be visible, requiring moving the updated tree view anyway.
- the automatic vertical moving of the updated tree view may cause the topmost element of the tree to be displayed with some distance from the top edge of the viewing window. Such displacements are quickly resolved once the user expands and scrolls through the next sub-levels of interest. For convenience, in another
- the mechanism includes a correction functionality moving the topmost element of the tree view to the top edge of the viewing window again, including moving the pointing cursor so that it stays at the same position with respect to the tree view.
- This correction functionality may be triggered on user request, e.g. by a keyboard or mouse control, or a multi-touch gesture, or automatically once such displacement would occur if configured as preferred by the user.
- FIG. 12 shows the view before the pointing cursor movement. Now the pointing cursor is moved to the left by a distance equivalent to one level of tree indentation, resulting in the tree view shown in Fig. 13 because, once the pointing cursor crosses the indentation of tree level 3 on its way, tree level 3 is collapsed automatically and the updated tree view is moved down automatically so that
- Concept_3_3, the direct super-element of Concept_3_3_3, is displayed at the vertical position at which Concept_3_3_3 was displayed before the update of the tree view. Further pointing cursor movement to the left by one level of tree indentation leads to the tree view shown in Fig. 14, with Concept_3 in Fig. 14 being displayed at the same vertical position as Concept_3_3 in Fig. 13.
- Automatic expanding or collapsing of tree levels may also be triggered by horizontal scrolling of the viewing window if the horizontal displacement of the tree view with respect to the unchanged pointing cursor position results in the horizontal pointing cursor position corresponding to a different tree level than before, with the automatic expanding restricted by the number of sub-levels of the active branch.
- scrolling the viewing window to the right is restricted by the element of the tree view reaching furthest to the right being right-aligned with the right edge of the viewing window, regardless of whether this element is actually visible within the viewing window.
- the viewing window allows to be scrolled to the right so that this indentation is clearly accessible by the pointing cursor. This results in the element of the tree view reaching furthest to the right being shown with some distance from the right edge of the viewing window if this element is actually visible and not long enough to clearly extend to this indentation.
- Fig. 15 shows the view before the scrolling.
- Fig. 15 shows the view before the scrolling.
- tree level 3 of the active branch are clipped by the right edge of the viewing window, so the user may also want to scroll the view to the right to be able to read more of the text of these elements.
- the viewing window is scrolled to the right by a distance equivalent to one level of tree indentation, resulting in the unchanged pointing cursor position horizontally corresponding to tree level 4, therefore tree level 4 of the active branch is expanded automatically, see Fig. 16.
- the viewing window is now scrolled to the right by one level of tree indentation again, resulting in the unchanged pointing cursor position horizontally corresponding to tree level 5 and tree level 5 of the active branch therefore being expanded automatically, see Fig. 17.
- the user may now try to expand further sub- levels of the active branch by scrolling the viewing window further to the right, but as there are no such sub-levels, this will only lead to the unchanged tree view being moved to the left within the viewing window until no element of tree level 5 of the active branch is clipped by the right edge of the viewing window anymore, given that all these elements are long enough to clearly extend to the indentation of tree level 6, making further displacement of these elements with respect to the right edge of the viewing window unnecessary. If the scrolling has been performed to be able to read the text of the elements of tree level 3 of the active branch instead, the user will probably move the pointing cursor to the left next until its horizontal position
- the updated tree view is also moved vertically so that the direct super-element of the tree level having been collapsed is vertically aligned with the unchanged pointing cursor position, similar to the behavior on moving the pointing cursor to the left under similar circumstances and for the same reasons. This may again lead to displacements of the topmost element of the tree view with respect to the top edge of the viewing window, which can be resolved as described above.
- FIG. 18 shows the view before the scrolling. Then the viewing window is scrolled to the left by a distance equivalent to one level of tree indentation, resulting in the unchanged pointing cursor position horizontally corresponding to tree level 4, therefore tree level 5 is collapsed automatically and the updated tree view is moved down automatically so that Concept_2_2_2_2, the direct super-element of Concept_2_2_2_2, is displayed at the vertical position at which
- Automatic expanding or collapsing of tree levels may also be triggered by vertical movement of the pointing cursor within the viewing window or vertical scrolling of the viewing window if the resulting vertical displacement of the pointing cursor with respect to the tree view causes an inactive branch to become the active branch or vice versa.
- the resulting update of the tree view may actually be more or less visible, up to the point that no change is visible at all.
- the proposed mechanism may automatically move the updated tree view vertically so that the actual pointing cursor position reflects the new logical pointing cursor position with respect to the updated tree view. This may again lead to displacements of the topmost element of the tree view with respect to the top edge of the viewing window, which can be resolved as described above.
- Vertical scrolling of standard tree views is typically restricted by the topmost element of the tree view being shown at the top edge of the viewing window and the bottommost element of the tree view being shown at the bottom edge of the viewing window.
- vertical scrolling according to the proposed solution is restricted by the topmost or bottommost element of the tree view being vertically aligned with the pointing cursor within the viewing window, for scrolling the viewing window up or down, respectively. This enables the user to scroll the whole tree view up or down beneath the unchanged pointing cursor position. Furthermore, the user can easily select how much of the tree view can be displayed above or below the pointing cursor by choosing a corresponding vertical pointing cursor position within the viewing window.
- the new logical pointing cursor position with respect to the tree view resulting from a vertical displacement of the pointing cursor with respect to the tree view caused by vertical movement of the pointing cursor within the viewing window or vertical scrolling of the viewing window is defined by means of a conceptual tree view called tailored tree view.
- the tailored tree view is defined to be the actual tree view with all elements and branches expanded up to the tree level corresponding to the horizontal position of the pointing cursor, regardless of the vertical pointing cursor position, with the horizontal pointing cursor position with respect to the actual and tailored tree view being the same.
- the vertical pointing cursor position with respect to the actual and tailored tree view is defined as follows: When the pointing cursor is placed above the topmost element of the actual tree view, it is conceptually also placed above the topmost element of the tailored tree view, with the same vertical distance from these elements. When the pointing cursor is vertically aligned with an element of the actual tree view, it is conceptually also vertically aligned with the same element of the tailored tree view, with the same vertical displacement with respect to these elements. When the pointing cursor is placed below the bottommost element of the actual tree view, it is conceptually also placed below the bottommost element of the tailored tree view, with the same vertical distance from these elements.
- the new logical pointing cursor position is defined to be the position the pointing cursor would have with respect to the tailored tree view if the vertical displacement of the pointing cursor with respect to the actual tree view was applied to the tailored tree view instead, with the same direction and distance.
- the pointing cursor When the pointing cursor is placed within the viewing window and above the topmost element of the tree view, there is no active branch, resulting in only the top-level elements of the tree being displayed, see Fig. 21 . From the position shown in Fig. 21 , the pointing cursor can be moved up and down within the viewing window without changing the tree view as long as the pointing cursor stays above the topmost element of the tree view. When the pointing cursor is moved down crossing the vertical boundary between the blank area and the topmost element of the tree view, it would also cross the vertical boundary between the blank area and the topmost element of the tailored tree view.
- the new logical pointing cursor position is vertically aligned with the topmost element of the tailored tree view, and the branch comprising this topmost element becomes the new active branch and is expanded automatically.
- the new logical pointing cursor position matches the actual pointing cursor position, and no vertical moving of the updated tree view is needed. For example, if the pointing cursor, in the viewing window shown in Fig. 21 , is moved down to the position shown in Fig. 22, the resulting tree view corresponds to Fig. 22 because, once the pointing cursor crosses the vertical boundary between the blank area and ConcepM on its way, the new logical pointing cursor position is vertically aligned with ConcepM and the branch comprising
- ConcepM becomes the active branch and is expanded up to tree level 2 due to the horizontal pointing cursor position.
- the pointing cursor When the pointing cursor is moved up within the viewing window crossing the vertical boundary between the topmost element of the tree view and a blank area above, it would also cross the vertical boundary between the topmost element of the tailored tree view and a blank area above. Therefore, the new logical pointing cursor position is just above the topmost element of the tree view, and the branch comprising this topmost element is no longer the active branch and is collapsed automatically. Due to the identity of the topmost element of the tree view and the topmost element of the tailored tree view, the new logical pointing cursor position matches the actual pointing cursor position, and no vertical moving of the updated tree view is needed.
- the resulting tree view corresponds to Fig. 21 , because, once the pointing cursor crosses the vertical boundary between ConcepM and the blank area above on its way, the new logical pointing cursor position is not vertically aligned with any tree element and the branch comprising ConcepM is no longer the active branch and is collapsed automatically.
- the pointing cursor When the pointing cursor is placed within the viewing window and below the bottommost element of the tree view, there is no active branch, resulting in only the top-level elements of the tree being displayed, see Fig. 23. From the position shown in Fig. 23, the pointing cursor can be moved up and down within the viewing window without changing the tree view as long as the pointing cursor stays below the bottommost element of the tree view. When the pointing cursor is moved up crossing the vertical boundary between the blank area and the bottommost element of the tree view, it would also cross the vertical boundary between the blank area and the bottommost element of the tailored tree view.
- the new logical pointing cursor position is vertically aligned with the bottommost element of the tailored tree view, and the branch comprising this bottommost element becomes the active branch and is expanded automatically.
- the bottommost element of the tree view may not be the same tree element as the bottommost element of the tailored tree view, this may result in the new logical pointing cursor position not matching the actual pointing cursor position. If this is the case, the updated tree view tree view is also automatically moved vertically so that the new logical pointing cursor position and the actual pointing cursor position are the same, resulting in the bottommost element of the updated tree view being displayed at the vertical position at which the bottommost element of tree view was displayed before the update of the tree view.
- the resulting tree view corresponds to Fig. 24, because, once the pointing cursor crosses the vertical boundary between the blank area and Concept_9 on its way, the new logical pointing cursor position is vertically aligned with Concept_9_9, the branch comprising Concept_9_9 becomes the active branch and is expanded up to tree level 2 due to the horizontal pointing cursor position, and the updated tree view is moved up so that Concept_9_9 is displayed at the vertical position at which
- the updated tree view is also automatically moved vertically so that the new logical pointing cursor position and the actual pointing cursor position are the same, resulting in the bottommost element of the updated tree view being displayed at the vertical position at which the bottommost element of tree view was displayed before the update of the tree view. For example, if the pointing cursor, in the viewing window shown in Fig. 24, is moved down to the position shown in Fig. 23, the resulting tree view corresponds to Fig.
- Pointing cursor movements crossing the vertical boundary between two vertically adjacent elements of the tree view result in a change of the active branch, with the currently active branch being collapsed automatically and the new active branch being expanded automatically.
- the new logical pointing cursor position is vertically aligned with the element of the tailored tree view directly above or below the tree element the pointing cursor was previously vertically aligned with, depending on the direction of the movement.
- the updated tree view is also automatically moved vertically so that the new logical pointing cursor position and the actual pointing cursor position are the same, resulting in the element of the updated tree view being vertically aligned with the pointing cursor being displayed at the vertical position at which the element of the tree view to which the pointing cursor has been moved was displayed before the update of the tree view. For example, if the pointing cursor in the viewing window shown in Fig. 25 is moved down to the position shown in Fig. 26, the resulting tree view corresponds to Fig.
- the branch comprising the tree element the new logical pointing cursor position is vertically aligned with becomes the active branch and is expanded automatically, depending on the horizontal position of the pointing cursor with respect to the tree view, restricted by the number of sub-levels of the active branch, and the updated tree view is automatically moved vertically so that the new logical pointing cursor position matches the actual pointing cursor position.
- Vertical scrolling of the viewing window is treated similar to vertical movement of the pointing cursor within the viewing window, with two notable differences: First, whereas vertical pointing cursor movement is always continuous, vertical scrolling may not be continuous, possibly resulting in the new logical pointing cursor position being vertically aligned with an arbitrary element of the tailored tree view instead of the topmost, the bottommost, or a vertically adjacent one. Second, whereas moving the pointing cursor within the viewing window above or below the tree view is unrestricted, vertical scrolling of the viewing window may be restricted as described above. In the shown embodiment, the vertical scrolling restrictions are applied. Furthermore, the following examples only illustrate vertical scrolling by distances equivalent to a multiple of the height of a tree element.
- the viewing window can only be scrolled down, resulting in the unchanged tree view simply being moved up within the viewing window as long as the new logical pointing cursor position is not vertically aligned with any element of the tailored tree view yet.
- the branch comprising this element becomes the active branch and is expanded automatically. If the update of the tree view leads to the new logical pointing cursor position not matching the actual pointing cursor position, the updated tree view is also automatically moved vertically so that the new logical pointing cursor position and the actual pointing cursor position are the same.
- the resulting tree view corresponds to Fig. 28 because the new logical pointing cursor position is vertically aligned with Concept_1_1_1 and the branch comprising Concept_1_1_1 becomes the active branch and is expanded up to tree level 3 due to the horizontal pointing cursor position.
- the new logical pointing cursor position already matches the actual pointing cursor position, no vertical moving of the updated tree view is needed.
- the viewing window can only be scrolled up, resulting in the unchanged tree view simply being moved down within the viewing window as long as the new logical pointing cursor position is not vertically aligned with any element of the tailored tree view yet.
- the branch comprising this element becomes the active branch and is expanded automatically. If the update of the tree view leads to the new logical pointing cursor position not matching the actual pointing cursor position, the updated tree view is also automatically moved vertically so that the new logical pointing cursor position and the actual pointing cursor position are the same.
- the resulting tree view corresponds to Fig. 30 because the new logical pointing cursor position is vertically aligned with Concept_9_9_7,the branch comprising Concept_9_9_7 becomes the active branch and is expanded up to tree level 3 due to the horizontal pointing cursor position, and the updated tree view is moved up so that the new logical pointing cursor position and the actual pointing cursor position are the same.
- the active branch changes. Therefore, the currently active branch is collapsed automatically, and the new active branch is expanded automatically. If the update of the tree view leads to the new logical pointing cursor position not matching the actual pointing cursor position, the updated tree view is also automatically moved vertically so that the new logical pointing cursor position and the actual pointing cursor position are the same. For example, if the viewing window shown in Fig. 31 is scrolled down by a distance equivalent to the height of 4 tree elements, the resulting tree view corresponds to Fig. 32 because the new logical pointing cursor position is vertically aligned with
- the branch comprising Concept_8_8_8 is no longer the active branch and is collapsed automatically, the branch comprising Concept_8_9_2 becomes the new active branch and is expanded up to tree level 3 due to the horizontal pointing cursor position, and the updated tree view is moved down so that Concept_8_9_2 is displayed at the vertical position at which Concept_8_8_8 was displayed before the update of the tree view. If the viewing window shown in Fig. 32 is scrolled up by a distance equivalent to the height of 4 tree elements, the resulting tree view
- the scrolling restrictions take effect, reducing the scrolling distance so that the new logical pointing cursor position is vertically aligned with the topmost or bottommost element of the tailored tree view, respectively. Therefore, the currently active branch, if there is one, is collapsed automatically, and the branch comprising the topmost or bottommost element of the tailored tree view, respectively, becomes the new active branch and is expanded automatically.
- the updated tree view is also automatically moved vertically so that the new logical pointing cursor position and the actual pointing cursor position are the same. This is the same behavior as the behavior caused by vertical scrolling of the viewing window directly leading to the new logical pointing cursor position being vertically aligned with the topmost or bottommost element of the tailored tree view, respectively.
